NFL Combine 2012: Top Performances from Guards Who Could Be Cincinnati Bengals

Combine weekend has come and gone, and with Andrew Luck and Robert Griffin III declining to throw, the main debate seems to be whether the combine really matters.

Well if you're not in the market for a QB, the combine remains the best opportunity to see your prospective picks in action, and in competition with a lot of other players.

While Cincy is set at the QB position, they are in desperate need of some protection for Andy Dalton at right guard. The 2012 combine saw all of the top-rated guards take to the field to show their stuff, and the results were impressive.

With performances in the book, and the numbers crunched, we can take a look at who might be the best fit in the Bengals banged-up offensive line.

Glenn ran an impressive unofficial 4.96 40-yard dash time that really caught everyone's attention, considering he weighed in at 345 pounds. His official time was a more measured 5.15, but with the potential that the previous time carries, the Bengals will be hard-pressed not to take a good hard look at Glenn.

He's a big player, and while 345 pounds may sound like a lot, it's spread well around his large frame. He put it to good use benching 225 pounds, 31 times on the day. His showing was a strong one-two punch combination of strength and speed.

With depth problems all over the O-line, the Bengals have to be impressed that Glenn played at right tackle, right guard and left tackle at Georgia.

Bobbie Williams may return for a victory lap in 2012, but he might not be healthy enough to play a full season, and with someone like Glenn ready to step up and replace him, or plug a gap wherever needed, he could be a great pickup.

His stock is on the rise.

David DeCastro, OG, Stanford

DeCastro more than justified his first-round tag this weekend, putting in a strong performance that was only eclipsed by likely top-five pick Matt Kalil.

He finished a solid second in the bench, clocking in at 34 lifts (Kalil had 30), and put up a middle-of-the-pack 5.43 40-yard dash time.

His performance in the bench was impressive, as expected. DeCastro is leaner than some of his fellow lineman, weighing in at 316 pounds, and he showed his impressive core strength with his 34 lifts.

He placed first in the Three Cone Drill and finished third in the 20-Yard Shuttle, good indicators of his footwork and his agility.

When you see a prospect like DeCastro put in a classy performance at the combine, it seems baffling that Cincy pulled the trigger on Andre Smith. That debacle still leaves a bitter taste in Cincinnati's mouth, despite Smith's improvements.

If the Bengals are going to spend one of their first-round picks on a guard, DeCastro would certainly be the antithesis to the style that Andre Smith brings to the table. He would also certainly not provide the Bengals with any headaches regarding his personal fitness either.

DeCastro got a lot of attention from coaches and was used as the go-to "demo" guy when explaining workouts, a testament to his natural ability and smarts.

He ticks all the boxes for Cincy when it comes to shoring up the right side, and could be a lock to play in stripes in 2012. However, the versatility that Glenn provides indicates that he could be more useful to the Bengals in their current state. Cincy is a sucker for big guys, and at 6'5", Glenn would certainly continue that theme.

The status of Bobbie Williams, coupled with how head coach Marvin Lewis intends to address the overall lack of depth on the offensive line will determine which one of these players is the best fit, and we will find out more as the draft draws closer.
